In a Tuesday interview with WISN radio's Dan O'Donnell, Nicholson lit into Ryan, Duffy, Sensenbrenner, and Grothman for supporting his primary opponent, Leah Vukmir, attacking them as "fail[ed]" members of the "political class" who only care about "winning their reelection, getting the money from the combination of lobbyists and big donors."

The full audio of Nicholson's interview is available here, but choice quotes that will be difficult to gloss over, no matter which candidate makes it out of the GOP Senate primary, include:

"Look, I am not of the political class -- and boy, does the political class know it, and boy do they fear it."

"And rightfully so: I'm going to call them account on all their failingsand things they have not gotten done in Washington."

"I'm also not going to go there and become part of this political class.The other members of the delegation -- they can be nervous about this all they want, but I'm not going there to be their friend."

"The political class cannot solve our issues. They have proven that the only thing that they are worried about is winning their reelection, getting the money from the combination of lobbyists and big donors that they need to kind of squeeze this thing through to the next time."

Washington Republicans do constantly side with corporate special interests at the expense of hardworking Wisconsinites.

But someone had better remind Kevin Nicholson not to throw stones when it comes to bashing 'big donors' -- because the glass house of his candidacy was just about entirely paid for by out-of-state billionaire megadonor Dick Uihlein.
